[ Upstream commit 919ddf8336f0b84c0453bac583808c9f165a85c2 ]
aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().
If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.
After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

[ Upstream commit 3d0f9342ae200aa1ddc4d6e7a573c6f8f068d994 ]
A static code analyzer tool indicates that the local variable called status
in the lpfc_sli4_repost_sgl_list() routine could be used to print garbage
uninitialized values in the routine's log message.
Fix by initializing to zero.

[ Upstream commit 0b149cee836aa53989ea089af1cb9d90d7c6ac9e ]
If scsi_execute_cmd returns < 0, it doesn't initialize the sshdr, so we
shouldn't access the sshdr. If it returns 0, then the cmd executed
successfully, so there is no need to check the sshdr. This has us access
the sshdr when we get a return value > 0.

commit 1abc900ddda8ad2ef739fedf498d415655b6c3b8 upstream.
Some firmware versions of the 9600 series SAS HBA byte-swap the REPORT
ZONES command reply buffer from ATA-ZAC devices by directly accessing the
buffer in the host memory. This does not respect the default command DMA
direction and causes IOMMU page faults on architectures with an IOMMU
enforcing write-only mappings for DMA_FROM_DEVICE DMA direction (e.g. AMD
hosts), leading to the device capacity to be dropped to 0:

Avoid such issue by always mapping the buffer of REPORT ZONES commands
using DMA_BIDIRECTIONAL (read+write IOMMU mapping). This is done by
introducing the helper function _base_scsi_dma_map() and using this helper
in _base_build_sg_scmd() and _base_build_sg_scmd_ieee() instead of calling
directly scsi_dma_map().

The command completion was done early while aborting the commands in driver

command completion via multiple paths causing system crash.
Hence complete the command early in unload path but within the lock to

commit c3d98b12eef8db436e32f1a8c5478be57dc15621 upstream.
The device does not come online when the target port is online. There were
multiple RSCNs indicating multiple devices were affected. Driver is in the
process of finishing a fabric scan. A new RSCN (device up) arrived at the
tail end of the last fabric scan. Driver mistakenly thinks the new RSCN is
being taken care of by the previous fabric scan, where this notification is
cleared and not acted on. The laser needs to be blinked again to get the
device to show up.
To prevent driver from accidentally clearing the RSCN notification, each
RSCN is given a generation value. A fabric scan will scan for that
generation(s). Any new RSCN arrive after the scan start will have a new
generation value. This will trigger another scan to get latest data. The
RSCN notification flag will be cleared when the scan is associate to that
generation.

commit ce2065c4cc4f05635413f63f6dc038d7d4842e31 upstream.
Firmware only supports single DSDs in ELS Pass-through IOCB (0x53h), sg cnt
is decided by the SCSI ML. User is not aware of the cause of an acutal
error.
Return the appropriate return code that will be decoded by API and
application and proper error message will be displayed to user.

[ Upstream commit 10157b1fc1a762293381e9145041253420dfc6ad ]
When a host is configured with a few LUNs and I/O is running, injecting FC
faults repeatedly leads to path recovery problems. The LUNs have 4 paths
each and 3 of them come back active after say an FC fault which makes 2 of
the paths go down, instead of all 4. This happens after several iterations
of continuous FC faults.
Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC
ACCESS STATE TRANSITION) instead of retrying.
[mwilck: The original patch was developed by Rajashekhar M A and Hannes
Reinecke. I moved the code to alua_check_sense() as suggested by Mike
Christie [1]. Evan Milne had raised the question whether pg->state should
be set to transitioning in the UA case [2]. I believe that doing this is
correct. SCSI_ACCESS_STATE_TRANSITIONING by itself doesn't cause I/O
errors. Our handler schedules an RTPG, which will only result in an I/O
error condition if the transitioning timeout expires.]

commit 7926d51f73e0434a6250c2fd1a0555f98d9a62da upstream.
Commit 321da3dc1f3c ("scsi: sd: usb_storage: uas: Access media prior
to querying device properties") triggered a read to LBA 0 before
attempting to inquire about device characteristics. This was done
because some protocol bridge devices will return generic values until
an attached storage device's media has been accessed.
Pierre Tomon reported that this change caused problems on a large
capacity external drive connected via a bridge device. The bridge in
question does not appear to implement the READ(10) command.
Issue a READ(16) instead of READ(10) when a device has been identified
as preferring 16-byte commands (use_16_for_rw heuristic).

commit 4254dfeda82f20844299dca6c38cbffcfd499f41 upstream.
There is a potential out-of-bounds access when using test_bit() on a single
word. The test_bit() and set_bit() functions operate on long values, and
when testing or setting a single word, they can exceed the word
boundary. KASAN detects this issue and produces a dump:
BUG: KASAN: slab-out-of-bounds in _scsih_add_device.constprop.0 (./arch/x86/include/asm/bitops.h:60 ./include/asm-generic/bitops/instrumented-atomic.h:29 drivers/scsi/mpt3sas/mpt3sas_scsih.c:7331) mpt3sas

commit 90e6f08915ec6efe46570420412a65050ec826b2 upstream.
The function mpi3mr_qcmd() of the mpi3mr driver is able to indicate to
the HBA if a read or write command directed at an ATA device should be
translated to an NCQ read/write command with the high prioiryt bit set
when the request uses the RT priority class and the user has enabled NCQ
priority through sysfs.
However, unlike the mpt3sas driver, the mpi3mr driver does not define
the sas_ncq_prio_supported and sas_ncq_prio_enable sysfs attributes, so
the ncq_prio_enable field of struct mpi3mr_sdev_priv_data is never
actually set and NCQ Priority cannot ever be used.
Fix this by defining these missing atributes to allow a user to check if
an ATA device supports NCQ priority and to enable/disable the use of NCQ
priority. To do this, lift the function scsih_ncq_prio_supp() out of the
mpt3sas driver and make it the generic SCSI SAS transport function
sas_ata_ncq_prio_supported(). Nothing in that function is hardware
specific, so this function can be used in both the mpt3sas driver and
the mpi3mr driver.

commit d09c05aa35909adb7d29f92f0cd79fdcd1338ef0 upstream.
Peter Schneider reported that a system would no longer boot after
updating to 6.8.4. Peter bisected the issue and identified commit
b5fc07a5fb56 ("scsi: core: Consult supported VPD page list prior to
fetching page") as being the culprit.
Turns out the enclosure device in Peter's system reports a byteswapped
page length for VPD page 0. It reports "02 00" as page length instead
of "00 02". This causes us to attempt to access 516 bytes (page length
+ header) of information despite only 2 pages being present.
Limit the page search scope to the size of our VPD buffer to guard
against devices returning a larger page count than requested.

Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

[ Upstream commit 06036a0a5db34642c5dbe22021a767141f010b7a ]
As of commit 7d1d86518118 ("[SCSI] libsas: fix false positive 'device
attached' conditions"), reset the phy->entacted_sas_addr address to a
zero-address when the link rate is less than 1.5G.
Currently we find that when a new device is attached, and the link rate is
less than 1.5G, but the device type is not NO_DEVICE, for example: the link
rate is SAS_PHY_RESET_IN_PROGRESS and the device type is stp. After setting
the phy->entacted_sas_addr address to the zero address, the port will
continue to be created for the phy with the zero-address, and other phys
with the zero-address will be tried to be added to the new port:
[562240.051197] sas: ex 500e004aaaaaaa1f phy19:U:0 attached: 0000000000000000 (no device)
// phy19 is deleted but still on the parent port's phy_list
[562240.062536] sas: ex 500e004aaaaaaa1f phy0 new device attached
[562240.062616] sas: ex 500e004aaaaaaa1f phy00:U:5 attached: 0000000000000000 (stp)
[562240.062680] port-7:7:0: trying to add phy phy-7:7:19 fails: it's already part of another port
Therefore, it should be the same as sas_get_phy_attached_dev(). Only when
device_type is SAS_PHY_UNUSED, sas_address is set to the 0 address.

[ Upstream commit 429846b4b6ce9853e0d803a2357bb2e55083adf0 ]
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver
prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)
WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8
replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended
to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array
declaration and clarify that it has flexible length. Also, adjust the
memory allocation size to match the change.

[ Upstream commit bb011631435c705cdeddca68d5c85fd40a4320f9 ]
Typically when an out of resource CQE status is detected, the
lpfc_ramp_down_queue_handler() logic is called to help reduce I/O load by
reducing an sdev's queue_depth.
However, the current lpfc_rampdown_queue_depth() logic does not help reduce
queue_depth. num_cmd_success is never updated and is always zero, which
means new_queue_depth will always be set to sdev->queue_depth. So,
new_queue_depth = sdev->queue_depth - new_queue_depth always sets
new_queue_depth to zero. And, scsi_change_queue_depth(sdev, 0) is
essentially a no-op.
Change the lpfc_ramp_down_queue_handler() logic to set new_queue_depth
equal to sdev->queue_depth subtracted from number of times num_rsrc_err was
incremented. If num_rsrc_err is >= sdev->queue_depth, then set
new_queue_depth equal to 1. Eventually, the frequency of Good_Status
frames will signal SCSI upper layer to auto increase the queue_depth back
to the driver default of 64 via scsi_handle_queue_ramp_up().

[ Upstream commit 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c ]
There are cases after NPIV deletion where the fabric switch still believes
the NPIV is logged into the fabric. This occurs when a vport is
unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the
fabric.
Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including
the fabric D_ID, removes the last ndlp reference and frees the ndlp rport
object. This sometimes causes the race condition where the final DA_ID and
LOGO are skipped from being sent to the fabric switch.
Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID
and LOGO are sent.

[ Upstream commit 321da3dc1f3c92a12e3c5da934090d2992a8814c ]
It has been observed that some USB/UAS devices return generic properties
hardcoded in firmware for mode pages for a period of time after a device
has been discovered. The reported properties are either garbage or they do
not accurately reflect the characteristics of the physical storage device
attached in the case of a bridge.
Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to
avoid calling revalidate twice") we would call revalidate several
times during device discovery. As a result, incorrect values would
eventually get replaced with ones accurately describing the attached
storage. When we did away with the redundant revalidate pass, several
cases were reported where devices reported nonsensical values or would
end up in write-protected state.
An initial attempt at addressing this issue involved introducing a
delayed second revalidate invocation. However, this approach still
left some devices reporting incorrect characteristics.
Tasos Sahanidis debugged the problem further and identified that
introducing a READ operation prior to MODE SENSE fixed the problem and that
it wasn't a timing issue. Issuing a READ appears to cause the devices to
update their state to reflect the actual properties of the storage
media. Device properties like vendor, model, and storage capacity appear to
be correctly reported from the get-go. It is unclear why these devices
defer populating the remaining characteristics.
Match the behavior of a well known commercial operating system and
trigger a READ operation prior to querying device characteristics to
force the device to populate the mode pages.
The additional READ is triggered by a flag set in the USB storage and
UAS drivers. We avoid issuing the READ for other transport classes
since some storage devices identify Linux through our particular
discovery command sequence.

[ Upstream commit 1197c5b2099f716b3de327437fb50900a0b936c9 ]
The myrb and myrs drivers use an odd way of implementing their sysfs files,
calling snprintf() with a fixed length of 32 bytes to print into a page
sized buffer. One of the strings is actually longer than 32 bytes, which
clang can warn about:
drivers/scsi/myrb.c:1906:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
drivers/scsi/myrs.c:1089:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
These could all be plain sprintf() without a length as the buffer is always
long enough. On the other hand, sysfs files should not be overly long
either, so just double the length to make sure the longest strings don't
get truncated here.

commit 8e68a458bcf5b5cb9c3624598bae28f08251601f upstream.
As of commit d8649fc1c5e4 ("scsi: libsas: Do discovery on empty PHY to
update PHY info"), do discovery will send a new SMP_DISCOVER and update
phy->phy_change_count. We found that if the disk is reconnected and phy
change_count changes at this time, the disk scanning process will not be
triggered.
Therefore, call sas_set_ex_phy() to update the PHY info with the results of
the last query. And because the previous phy info will be used when calling
sas_unregister_devs_sas_addr(), sas_unregister_devs_sas_addr() should be
called before sas_set_ex_phy().
